About the position

At DoorDash, our Data Scientists and ML Engineers have the opportunity to dive into a wealth of delivery data to improve company-wide ML workflows such as Search & Recommendations, Dasher Assignment, ETA Prediction, and Dasher Capacity Planning. You will join a small team to build systems that empower efficient machine learning at scale. This is a hybrid opportunity in San Francisco, Sunnyvale, or Seattle. You will be responsible for building a world-class ML platform where models are developed, trained, and deployed seamlessly. You will work closely with Data Scientists and Product Engineers to evolve the ML platform as per their use cases. Your role will involve building high-performance and flexible pipelines that can rapidly evolve to handle new technologies, techniques, and modeling approaches. You will also work on infrastructure designs and solutions to store trillions of feature values and power hundreds of billions of predictions a day. Additionally, you will help design and drive directions for the centralized machine learning platform that powers all of DoorDash's business, improving the reliability, scalability, and observability of our training and inference infrastructure.
